Hello everyone. I am currently hooking up my new single deck radio into 97 f150 5.4. I have a massive problem though. All the diagrams online have wire colors on the diagram that I don't have at all. I manged to get the radio on and such but no speakers. Diagrams like this

Left Front Speaker Positive Wire (+): Gray/Light Blue
Left Front Speaker Negative Wire (-): Tan/Yellow
Right Front Speaker Positive Wire (+): White/Light Green
Right Front Speaker Negative Wire (-): Dark Green/Orange
Car Audio Rear Speakers Size: N/A
Car Audio Rear Speakers Location: N/A
Left Rear Speaker Positive Wire (+): Orange/Light Green
Left Rear Speaker Negative Wire (-): Light Blue/White
Right Rear Speaker Positive Wire (+): Orange/Red
Right Rear Speaker Negative Wire (-): Brown/Pink

From modifiedlife.com are no help. Behind the deck I do have those wire colors but they run down below into a box and come up in completely different colors. I don't want to rip apart my dash to find them. Any help with the speakers guys?
